Ok those who own Kessils, either the 150s or the 350s, what sort of MH equivalent (assume bluer bulbs and not those "PAR buster" 6500-10000K spectrum bulbs) are they? 150w? 250w? My 250w MHs are probably on their way out, and I'm looking to replace them with LEDs and I'm torn between Kessils and a DIY fixture (depends how much effort I really want to put into it). Currently I have a couple T5 bulbs (blue) and 2 -250w MH bulbs over my 4' x 3' tank, at $400 a pop per Kessil 350 it could get awfully expensive to replace them.
